Answer:
Step-by-step explanation:
Given that the time to complete a standardized exam is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
P(completing exam before 1 hour)
= P(less than an hour) = P(X<60)
=P(Z<
)
=0.5-0.34=0.16
i.e. 16% of students completed the standardized exam.
If it is 50 pages in an hour, half an hour would be 25 pages, and if it is 40 pages in an hour it would be 20 pages in half an hour, the answer is 5 pages more in half hour
1/5 of 55 is 11, you multiply 11 by 20 and you get 220. Total there is 1100 minutes of tv so then you subtract 220 from 1100 and there is 880 minutes of tv without commercials then you divide that by 60 and you get 14 hours and 20 minutes.
